Expand Your Horizons on Catalina Island

The Wrigley Institute Catalina Residential College, based at the Wrigley Marine Science Center on Catalina Island, is your campus-away-from-campus for learning about the environment and sustainability. We offer residential courses on a variety of topics, with a focus on interdisciplinary and hands-on learning for future environmental leaders.

Sound like you? Some of our Maymester classes still have available spaces and will be filled on a rolling basis, so don’t wait to apply! Or keep scrolling for details on our other Catalina Residential College programs.

Charting a Sustainable Future at USC

Nicole Summerfield’s Catalina Residential College experience was so transformative that she enrolled not once, but twice. From investigating social perceptions of climate interventions to entering an underwater world of ecosystem research, Nicole used her visits to the island as stepping stones toward a more sustainable future, both for herself and for the planet.

“My fondest memories and most impactful learning experiences at USC were made possible by the Catalina Residential College. It was an experience like no other: it deeply ingrained in me the beauty and importance of preserving our natural world, and I would come back every year if I could.”

Our Maymester and Julymester courses are generally capped at 15-20 people, so you get the chance to form strong connections with other students in the program.

By immersing yourself in the life of Catalina Island, you gain round-the-clock opportunities (like this nighttime plankton lab) to explore a unique, pristine ecosystem just 22 miles from Los Angeles.

Many Catalina Residential College programs include co-curricular activities where you can learn a variety of fun and useful water skills, such as free diving, how to operate small boats, and more.

The Catalina Residential College isn’t just about natural science: our programs also include learning opportunities in the social sciences and humanities. Here, a student uses VR goggles to view an immersive model of an underwater archaeological site.

All Catalina Residential College programs incorporate some kind of immersive, hands-on learning or research. Here, students log data from an aquaculture experiment taking place in WMSC’s bluehouse, a large lab that is specially equipped for ocean science experiments.

Oceanography students and their professor set off on a sampling trip aboard the research vessel Yellowfin. The Catalina Residential College provides numerous opportunities to engage in hands-on research, mentored by USC’s world-class faculty.

Thanks to the Catalina Residential College’s small class sizes, students learn directly from USC faculty and can easily obtain any extra support they need to be successful. (Plus, who doesn’t love lectures on the beach?)

Outside class time, Catalina Residential College students have ample opportunity to explore the island’s ecology through guided hikes, kayak excursions, snorkels, field trips, and more.

Choose Your Own (Island) Adventure

For a few days to a full month, enroll in a Wrigley Institute Catalina Residential College experience to see the environment and sustainability in a whole new way. Located in pristine surroundings just 22 miles off the coast of Los Angeles, our satellite campus provides a unique lens on how conservation, human activity, and a host of other factors affect our planet.

Maymester

Our Maymester program is an immersive, four-week living/learning experience that couples specialized coursework with interdisciplinary exploration around urban oceans. Students register for and attend core classes on the island but also collaborate across disciplines on projects and experience Catalina as a group.

Julymester

Like Maymester, our Julymester is an immersive, four-week program that encourages connections within and across disciplines. Students take a core class while also participating in cohort-wide learning opportunities focused on the theme of sustainability.

Weekend Workshops

Gain real-world professional skills through activity-packed weekends at the Wrigley Marine Science Center. Open to first or second year USC undergraduates, these 2- and 3-day courses teach skills for environmental and sustainability careers in a variety of fields.
